</div>
<div id="winchm_template_container">
	<div id="winchm_template_content"><div id="mainSection"><p>The method <a href="#Bookmark394"><b>GetDebuggeeType</b></a> returns the nature of the current target (for example, whether it is a kernel-mode or user-mode target), and how the <a href="#Bookmark192">debugger engine</a> is connected to it.</p>
<p>If the target is a crash dump file file, the method <a href="#Bookmark469"><b>GetDumpFormatFlags</b></a> will indicate what information is contained in the dump.</p>
<h3><a id="target_s_computer"></a><a id="TARGET_S_COMPUTER"></a>Target's Computer</h3>
<p>The page size of the target's computer is returned by <a href="#Bookmark418"><b>GetPageSize</b></a>.  <a href="#Bookmark433"><b>IsPointer64Bit</b></a> will indicate if the computer uses 32-bit or 64-bit addresses.</p>
<div class="alert"><b>Note</b>  Internally, the debugger engine always uses 64-bit addresses for the target.  If the target only uses 32-bit addresses, the engine automatically converts them when communicating with the target.</div>
<div> </div>
<p>The number of processors in the target's computer is returned by <a href="#Bookmark416"><b>GetNumberProcessors</b></a>.</p>
<p>There are three different processor types associated with the target's computer:</p>
<ul>
<li>
<p>The <i>actual processor type</i> is the type of the physical processor in the target's computer. This is returned by <a href="#Bookmark389"><b>GetActualProcessorType</b></a>.</p>
</li>
<li>
<p>The <i>executing processor type</i> is the type of the processor used in the currently executing processor context. This is returned by <a href="#Bookmark402"><b>GetExecutingProcessorType</b></a>.</p>
</li>
<li>
<p>The <i>effective processor type</i> is the processor type the debugger uses when interpreting information from the target -- for example, setting breakpoints, accessing registers, and getting stack traces.  The effective processor type is returned by <a href="#Bookmark396"><b>GetEffectiveProcessorType</b></a> and can be changed using <a href="#Bookmark450"><b>SetEffectiveProcessorType</b></a>.</p>
</li>
</ul>
<p>The effective processor type and executing processor type may differ from the actual processor type -- for example, when the physical processor is an x64 processor and it is running in x86 mode.</p>
<p>The different executing processor types that are supported by the physical processor on the target's computer are returned by <a href="#Bookmark419"><b>GetPossibleExecutingProcessorTypes</b></a>.  The number of these is returned by <a href="#Bookmark415"><b>GetNumberPossibleExecutingProcessorTypes</b></a>.</p>
<p>The list of processor types that is supported by the debugger engine is returned by <a href="#Bookmark427"><b>GetSupportedProcessorTypes</b></a>.  The number of supported processor types is returned by <a href="#Bookmark417"><b>GetNumberSupportedProcessorTypes</b></a>.</p>
<p>The names (full and abbreviated) of a processor type are returned by <a href="#Bookmark420"><b>GetProcessorTypeNames</b></a>.</p>
<p>The current time on the target's computer is returned by <a href="#Bookmark468"><b>GetCurrentTimeDate</b></a>.  The length of time the target's computer has been running since the last boot is returned by <a href="#Bookmark467"><b>GetCurrentSystemUpTime</b></a>.  Time information may not be available for all targets.</p>
<h3><a id="target_versions"></a><a id="TARGET_VERSIONS"></a>Target Versions</h3>
<p>The Windows version running on the target's computer is returned by <a href="#Bookmark520"><b>GetSystemVersionValues</b></a> and the <a href="#Bookmark251"><b>Request</b></a> operation <a href="#Bookmark258"><b>DEBUG_REQUEST_GET_WIN32_MAJOR_MINOR_VERSIONS</b></a>, and a description of the Windows version is returned by <a href="#Bookmark518"><b>GetSystemVersionString</b></a>.  Some of this information is also returned by <a href="#Bookmark429"><b>GetSystemVersion</b></a>.</p></div></div>
